FOLDING MOP-WRINGER.

Specification of Letters Patent.

Patented Aug. 3, 1909.

Application filed September 11, 1908. Serial No. 452,552.

To all whom it may concern:

Be it known that I, FRANK H. JAEGER, a citizen of the United States ofAmerica, residing at the city of St. Louis, in the State of Missouri,have invented certain new and useful Improvements in Folding Mop Nringers, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification.

My invention relates to a mop wringer, and it has for its object theproduction of a device of this character which comprises a suitable mainframe and wringing rollers, the parts of the main frame being soconnected to each other, as to permit of the wringer being folded into acompact condition, when not in use, and unfolded and retained in anunfolded position in an efficient manner, when the wringer is put intoservice.

Figure I is a perspective view of my mop -wringer in condition for use,showing the parts as they appear when a mop is being wrung in theemployment of the device. Fig. II is a top or plan view of the wringerin its unfolded condition. Fig. III is a vertical longitudinal sectionthrough the wringer in its unfolded condition. Fig. IV is a longitudinalvertical section taken through the wringer in its folded condition andillustrating the manner in which it may be suspended from a suitablesupport when it is not in use. Fig. V is an enlarged vertical crosssection taken on line VV, Fig. III, through the leg spreader of the mainframe at the lo cation of the detent by which the leg spreader is heldfrom movement when the main frame of the wringer is in unfoldedcondition.

In the accompanying drawings: 1 designates the inclined rear legs of themain frame of my wringer which are connectedby an intermediate crosspiece 2, and an upper cross piece 3.

4 are transverse side boards secured to the rear legs 1 at their upperends and extending forwardly from said rear legs.

5 are the inclined front legs of the main frame which are pivotallyconnected at their upper ends to the side boards 4 through the medium ofa cross rod 6 that extends through the front legs. The cross rod 6 hasfitted to it at its outer ends collars 7 that serve to hold the rod inposition in the side boards and rent legs.

8 is a cross piece attached to the front ends of the side boards 4 andprojecting outwardly from the outer faces of said side boards to formsteps that restrict the movement of the front legs when they are movedforward or in a direction away from the rear legs 1 by swinging themupon the cross rod 6. When the front legs are spread as stated, therebyestablishing the unfolded condition of the main frame of the wringer,the said legs are retained in their spread positions by a suitable hookor latch 9 attached to the cross piece 8 and arranged to engage an eye10 seated in one of the front legs, as seen in Fig. I. The rear andfront legs are spread from each other by a spreader which will next bedescribed.

11 and 12 are cross bars secured to the rear legs 1 near their lowerends, and the former of which has attached to it at its rear side, adouble-arm bracket 13.

14 is a cross bar attached to the front legs Znear their lower ends andto which is afliXed at its rear side a double-arm bracket 15.

16 are outer spreader bars pivotally connected to the arms of thedouble-arm bracket 13 at their outer ends and 17 is a pivot rod thatconnects said outer spreader bars and extends transversely between them.

18 are inner spreader bars having slot and pin connection with the armsof the doublearrn bracket 15 attached to the front cross bar 14. Theselast named inner spreader bars are loosely fitted at their inner ends tothe pivot rod 17 whereby they are joined to the outer spreader bars 16in a manner to permit of the outer spreader bars 16 and inner spreaderbars 18 being simultaneously elevated and lowered at their inner ends.The outer spreader bars 16 are provided with extensions at their innerends that project beyond the joints of their pivotal connection to thepivot rod 17 and upon these extensions are stop fingers 16, see Figs. Iand III that are adapted to enter the notches 18 in the upper edges ofthe inner spreader bars 18 when the outer and inner spreader bars arelowered into horizontal positions and into alinement with each other tohold the front and rear legs of the main frame of the wringer in aspread condition. Each of the outer spreader bars 16 is provided at itsinner end with a spring latch plate 16 that projects beyond the innerend of said outer spreader bar and contains an a erture 16*. In theinner spreader bar 18 ocated alongside of the outer spreader bar bearingthe latch plate just mentioned is a latch pin 19 that is so located inthe inner spreader bar 18 as to provide for its entering the aperture 16in the latch plate 16 when the outer spreader bars 16 and inner spreaderbars 18 are lowered into alinement with each other to hold the legs 1and 5 spread from each other. The latch pin 19 is preferably in the formof a screw that extends through the inner spreader bar 1.8 in which itis seated and has threaded engagement therewith. This screw ispreferably retained in the inner spreader bar after it been introducedthereinto-by a jam nut 20, see Fig. V.

21 designates a lift spring that is attached at its outer end by a strapplate to the lower cross bar 12 secured to the rear legs 1, and which isfitted or lapped at its inner end to the pivot bolt 17 that connects theouter spreader bars 16 and inner spreader bars 18. This lift springserves to elevate the leg spreading members 16, 18 and 17 when the mainframe of the wringer is to be folded after the latch pin 19 has beendisengaged from the latch plate 16. i

22 designates a wringer roller that is provided with a shaft-23 which isjournaled in suitable bearings supported by the main frame of thewringer and has fixed to it a crank handle 24 by which the roller may berotated.

25 designates a pressure roller supporting frame that is rockablymounted upon the cross rod 6 that unites the front legs 5 of the mainframe to the side boards 4 of said main frame. The frame 25 projectsboth inwardly and outwardly from said cross rod.

26 is a pressure roller loosely mounted in the forward ends or arms ofthe frame 25 and adapted to be moved into juxtaposition to the wringerroller 22. The roller sup porting frame 25, is provided with a coverproviding a drain plate or board 27 having rocking movement with theroller supporting frame.

In the practical use of my mop wringer, a bucket or other vessel isplaced upon the spreader bars of the wringer as indicated in dottedlines Fig. III with the mop that is to be wrung seated in the bucket andhaving its handle extending upwardly between the wringer roller 22 andthe pressure roller 26. The mop is then lifted by its handle until itsbutt end is positioned adjacent the wringer roller after which .thepressure roller is moved upwardly toward the wringer roller and the mopby downward pressure upon the outer end of the pressure roller frame 25.The operator may then lay the handle of the mop upon the drain board 27and while continuing to exert downward pressure upon the outer end ofthe frame 25, turn the crank handle 24 of the wringer roller, wherebythe mop is fed upwardly and water wrung therefrom, during the movementof the mop be tween the two rollers. When the wringer is to be laidaside, the latch 9 is disengaged from the hook 10, thereby disconnectingthe front legs 5 from the cross piece 8 carried by the side boards 4 andthen the spreading members connecting the front and rear legs areunfastened at their adjacent ends. The entire frame of the wringer maythen be folded in condition illustrated in Fig. IV and be suspended froma suitable hanger by the application of the pressure roller supportingframe to said hanger, as illustrated in said view.

I claim':

1. In a mop wringer, the combinationof a rear main frame leg sectionprovided with side boards extending forwardly therefrom, a forward mainframe leg section pivotaliy connected to said side boards, rollerssupported by said frame members, means whereby said leg sections may beheld spread from each other; said last named means comprising spreaderbars connected to said leg sections at their outer ends and pivotallyconnected to each other at their inner ends, and a spring carried by oneof said leg sections and. having connection with said bars at theirpoint of pivotal. connection to each other, whereby said bars may belifted at their point of pivotal connection, substantially as set forth.

2. The combination. of the rear legs having a cross bar and a double armbracket secured to its cross bar, forward legs having a cross bar and adouble arm bracket secured to its cross bar, the outer spreader barspiv- FRANK H. JAEGER. In presence of WM. H. SooTT, E. M. HARRINGTON.
